MARQUETTE — Don Durley calls them the “Deltagander Blues.” It’s the music that his restaurant is featuring every other Wednesday evening at present when Fast Eddie and Da Bones Man start to wail. Durley’s restaurant in downtown Marquette is called Lagniappe, which means “a little something extra or a little more than expected.” That’s what patrons get on those Wednesday nights: Some great music to enjoy while feasting on the Cajun-Creole food. “We’re lagniapping Lagniappe,” Durley said. “We are re-creating our identity as a blues club. We want to give a venue to that style of music. There’s a lot of talent in the Upper Peninsula so we’re excited about it.” When warmer weather takes hold, Durley plans to expand the musical offerings to include The Billy Butcher Band, which plays bayou-Cajun style tunes, every Monday. “That’s why I call what we’re doing the ‘Deltagander Blues.’ It’s Delta music played by Michiganders,” Durley said.
